Between walking and running, human gaits can cover a wide range of speeds; for example, at low speeds, the metabolic rate of walking is lower than that of running in a slow jog. The opposite also is true: at high speeds, the metabolic cost of running is lower than that of speed-walking.

The latest research indicates that well-integrated HMI (human-machine interface) systems lead to more attentive users that better retain task-related information and stay focused for longer with less reported effort. These systems also fit into the wider development trends in off-highway machines that affect operator fatigue in day-to-day tasks.

Back pain is inevitable with constrained posture over a number of hours. Permanent damage such as premature spine wear is not uncommon in people who do not adopt proper ergonomic posture. The same applies to those who frequently lift heavy objects.

Comparison Study of Malaysian Driver Seating Position in SAEJ1517 Accommodation Model

A key element in an ergonomically designed driver’s seat in a car is the correct identification of driver seating position and posture accommodation. Current practice by the automotive Original Equipment Manufacturer (OEM) is to utilize the Society of Automotive Engineering (SAE) J1517 standard practice as a reference. However, it was found that utilizing such guidelines, which were developed based on the American population, did not fit well with the anthropometry and stature of the Malaysian population. This research seeks to address this issue by comparing the SAE J1517 Model against Malaysian preferred driving position. A total of 62 respondents were involved for the driver seating position and accommodation study in the vehicle driver’s seat buck mockup survey and measurements. The results have shown that the Malaysian drivers prefer to sit forward as compared to the SAE J1517 Model and have shorter posture joint angle. This could significantly affect the design of the driver seat positions and layout of other driving elements, suggesting a need to reconsider its application, in particular for the Malaysian population.

Development of the Next Generation Flexible Tooling System

Larry Kirby, Ronald Weddle
Published 2019-03-19 by SAE International in United States
Flexible Tooling Systems have been developed as a reconfigurable part support system to enable trimming of multiple part geometries utilizing a single router or waterjet. The driver for this development has been improved part quality, elimination of ergonomic issues associated with manually trimming, and the elimination of cost for part number specific hard tooling and the associated cost for manufacturing, maintenance, and storage. This paper will briefly trace the evolution of aerospace parts trimming history. The remainder of the report will focus on the technical objectives associated with the development of the Next Generation Flexible Tooling System, how they were achieved including the process for validation of each support location in aircraft coordinates. This system is designed to increase part holding accuracy with specific support location validation, and significantly reduce system maintenance costs in wet or dry environments.

Encore Automation-Karl Schuknecht
Published 2019-03-19 by SAE International in United States
The surface preparation of the fuselage prior to painting is largely done manually in the Aerospace Industry; utilizing scrubbers, sanders, chemicals, and manlifts resulting in safety and ergonomic issues without delivering a consistent result. The automation of the process employing robots, vision systems, machine movers, and automated process equipment provided the following benefits: Improved Safety and ErgonomicsReduced exposure to hazardous materials and working conditionsImproved Consistency and QualityImproved Production Capabilities and Reduced Labor CostsReduced Material UsageLess weightLower environmental risksLower costThis paper will describe the equipment used and the process changes required to automate the surface preparation process, then discuss the benefits that were realized.

The Ergonomics of Robotics: Part 2

  • Magazine Article
  • TBMG-33988
Published 2019-03-01 by Tech Briefs Media Group in United States

In this two-part series on robotics and wearable devices, highlighted the wearable device product category. Part 2 moves the discussion from wearable devices to how robotic surgery is changing the future of surgery. This article discloses five fundamental human factors that must be addressed in the design of any robotic surgical system. And not unlike part 1 on wearable devices, the terms ergonomics and human factors engineering are used interchangeably.

Published 2019-02-06 by SAE International in United States
This Aerospace Recommended Practice (ARP) addresses direct touch interactive electronic display systems installed in the cockpit/flight deck for use by pilots. Direct touch refers to interactivity where the display screen is the input surface. This entire direct interactive electronic display system is referred to as the touch system throughout this document and covers those items related to direct interactive touch on display devices. In cases where only the display and touch device are being considered, this is referred to as the touch screen. The ARP covers system design guidelines as well as the considerations and recommendations for system performance and human factors. This ARP is intended to cover systems installed in 14 CFR Part 23, 25, 27, and 29 aircraft. As an ARP this document collects what are considered good practices by developers, users, and regulators of touch systems. The state of touch technology and the application of that technology is still evolving. As a result, it is premature to develop quantitative guidance for some key touch characteristics. In addition to the recommendations, this document…

Published 2019-02-01 by Tech Briefs Media Group in United States

The wearable device product category is exploding in healthcare design. Wearing these sensory devices that continuously collect, measure and report the user's physiology, exercise behavior, lifestyle activity, and health status requires three key human factors in the design. In this two-part series on robotics and wearable devices, part 1 dives into wearable designs by taking a look at the research being done now that eliminates the device altogether.

Improved Clutch Pedal Ergonomic Position through Adjustable Clutch Pedal Assembly as per Anthropometry

Tata Technologies, Ltd.-Chandrakant Gopalrao Musale, Ashish Deshpande, Sachin Latare, Mangesh Deshmuk
Published 2019-01-09 by SAE International in United States
In automotive sector, worlds demanding more riding comfort so accelerator, brake and clutch pedals plays important roles in providing comfort or discomfort to driver. Now days automotive OEMs paying more attentions on providing comfortable ergonomics positions of pedals but it is difficult meet the requirement of each and every (all percentile populations) person because of packaging/manufacturing/costing constraint.Here we are providing the solution to meet the requirement of comfortable ergonomics position as per drivers wish for all kind of persons/drivers (5th percentile to 95th percentile) by providing the adjustable clutch pedal assembly with simple mechanism.Currently adjustment provided in driver’s seat to adjust the comfortable driving position which provide the comfortable positions for 25th percentile to 95th percentile peoples also this arrangement having some limitations such as space constraint in cabin also high belly with low height persons may face the issue of belly obstacle while steering the vehicles. To overcome these issues adjustment in the pedal is must for comfortable driving position.
